Function WriteConfigMW

cli/server.go:1500–1525

writeConfigMW will prevent the main command from running if the write-config flag is set. Instead, it will marshal the command options to YAML and write them to stdout.

(cfg *codersdk.DeploymentValues)

// flag is set. Instead, it will marshal the command options to YAML and write
// them to stdout.
func WriteConfigMW(cfg *codersdk.DeploymentValues) serpent.MiddlewareFunc {
	return func(next serpent.HandlerFunc) serpent.HandlerFunc {
		return func(inv *serpent.Invocation) error {
			if !cfg.WriteConfig {
				return next(inv)
			}

			opts := inv.Command.Options
			n, err := opts.MarshalYAML()
			if err != nil {
				return xerrors.Errorf("generate yaml: %w", err)
			}
			enc := yaml.NewEncoder(inv.Stdout)
			enc.SetIndent(2)
			err = enc.Encode(n)
			if err != nil {
				return xerrors.Errorf("encode yaml: %w", err)
			}
			err = enc.Close()
			if err != nil {
				return xerrors.Errorf("close yaml encoder: %w", err)
